Through ongoing archaeological and cultural research, the Umm el-Jimal Project is uncovering fascinating secrets about this place. Although located on the semi-arid plain of the Hauran, its residents devised an ingenious water storage system through a network of canals and reservoirs that collected runoff water from kilometres away to sustain thousands of people, their animals and agricultural practices. Ancient denizens used abundant black basalt from the region’s volcanic plain to construct sturdy, insulated structures that reached up to six stories. Techniques such as corbelling allowed most buildings to contain multiple floors, while cantilevered stairways provided access to these upper storeys.
